What is the coverage area and its limitation?
Generally, the coverage area radius for the Home Zone is around 15 meters (roughly the end-end distance in a HDB 5-room flat). The connectivity will be most ideal if the distance between the mobile handset and the Home Zone Access Point is within 5 metre radius. The diagram below shows the Home Zone Access Point signal strength measured in the typical HDB 5-Room flat where the Home Zone Access Point is placed in the living room. It shows some signal degradation at certain locations e.g when the mobile is trying to access the Home Zone Access Point from one of the bedroom. The walls between the Home Zone Access Point and mobile handsets cause the signal strength to reduce. Signal Interference Your mobile handset will continuously scan for mobile channel frequency. It will generally log on to dominant signal for best reception. When trying to access near an opening of the house, say a window, the signal strength can also degrade as there may be interference from an external mobile base s
